Try this out and let me know what you think. I am inclined to use this with a good set of headphones. Users have shown a preference for leaving the wifi on to aid in the phenomena while using headphones. Experiment for yourself and comment below. 1. *For best results turn your devices volume to 10, place on a hard surface with your device speaker facing down and prop the device up 1/2 to 1 inch above the surface. External speakers are recommended if you are using a phone without a loud speaker. Tablet speakers have been found to work very well and seem to be loud enough on their own. 2.
